Fingerprint-Activated Encryption Module for Classified Data Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data retention systems face privacy issues due to lack of robust security measures, especially when personal data is accessed through centralized management and network storage, leading to potential exposure of classified information.
Innovation Solution
A data retention device with a dedicated storage module, an encryption module, and a lock fastener module, where power is activated by fingerprint recognition, ensuring only authorized access through a specific data plug and socket connection, and encrypted data is stored in a separate module, preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If centralized data management and network storage are used, then data accessibility and backup are improved, but data privacy and security deteriorate
Solution Approach 1:
The system divides data storage into two separate modules: a general storage module for public data and a dedicated storage module for classified information. This segmentation isolates sensitive data from centralized network storage, maintaining accessibility while enhancing privacy security.
Solution Approach 2:
The dedicated storage module is physically extracted from the main device body and requires separate installation. This extraction removes classified data from the centralized management system, eliminating the privacy risks associated with network storage while preserving data accessibility through the encryption module.
2Ease of operation
If encryption module is integrated into main device, then ease of operation is improved, but data security deteriorates
Solution Approach 1:
The encryption module is segmented as a separate, independently installable component rather than being integrated into the main device. This allows the encryption functionality to be applied to data in the dedicated storage module without compromising security, while maintaining ease of operation through the encryption key management system.
3Adaptability or versatility
If physical connection interface is provided, then adaptability is improved, but security risk increases
Solution Approach 1:
The physical connection interface is extracted and placed on a separate dedicated storage module rather than being integrated into the main device body. This isolation limits the attack surface, allowing external connectivity while reducing the risk of unauthorized access to the main system.
Solution Approach 2:
A locking element acts as an intermediary between the physical connection interface and the internal systems. This locking mechanism must be activated through authorized procedures before the interface can be connected, providing an additional security layer that maintains adaptability while preventing unauthorized access.

AI summary
The present disclosure relates to a data retention device designed for security of digital classified information. In the data retention device, a power source component is first activated by a fingerprint switch. When a data plug of a dedicated storage module and a data socket of an encryption module are connected with each other, a locking element in the encryption module is fixed at a locking hole in the dedicated storage module and the encryption module is electrically connected to the dedicated storage module through the data socket. Then, with an external component of the encryption module electrically connected to an external device, classified information is accessed, encrypted in the encryption module and saved in the storage element.
